Recently I started to answer some questions on Stack overflow in vhdl topics (It's the only subject where I am a bit competent). When there is a question, most of the experimented members answer the question in comments (especillay when it's a very specific question or a bad question).

I also got a downvote when I answer a question where the developper made a syntax error (that was the real reason of his problem and he accepted it).

So what should I do :
- Answer in comments when the question is not "interesting" for the community ?
- Answer only if there is no answer in comments ?
- Answer even if the answer is already in comments ?
